The Cu(II) complex of Aβ40 peptide in ammonium acetate solutions. Evidence for ternary species formation

Fluorimetric Cu(II) titrations of Alzheimer’s disease (AD) Aβ40 peptide at various ammonium acetate concentrations demonstrated that ternary Cu(Aβ40)L complexes are formed with buffer components L, thereby providing a novel perspective on Cu(II)–Aβ interactions.
